12 Provisioning Oracle Linux 7 The binaries for the 12c database have already been preinstalled on the Oracle Linux VM. They are held in the /u01/app/oracle directory. The password for this VM is oow. Terminal Open a new terminal session by double-clicking on the Terminal icon on the desktop: Create a Directory Structure Each of the shares created on the storage will need a local directory to contain the mounts on the Oracle Linux VM. Please use the following locations: $ sudo mkdir -p /zfssa/hol9715/datafiles $ sudo mkdir -p /zfssa/hol9715/fra $ sudo mkdir -p /zfssa/hol9715/logs Edit /etc/fstab for the New Shares The entries have already been populated inside of /etc/fstab: $ cat /etc/fstab # Oracle DB 12c HOL :/export/HOL9715/datafiles /zfssa/hol9715/datafiles nfs rw,bg,hard,nointr,rsize= ,wsize= ,tcp,vers=4,timeo=600,noac :/export/HOL9715/fra /zfssa/hol9715/fra nfs rw,bg,hard,nointr,rsize= ,wsize= ,tcp,vers=4,timeo=600,noac :/export/HOL9715/logs /zfssa/hol9715/logs nfs rw,bg,hard,nointr,rsize= ,wsize= ,tcp,vers=4,timeo=600,noac 0 0 Mount the Shares $ sudo mount -a Enable dnfs The entries have already been populated inside of $ORACLE_HOME/dbs/oranfstab: $ su oracle $ cat $ORACLE_HOME/dbs/oranfstab server: path: nfs_version: nfsv4 export: /zfssa/hol9715/datafiles mount: /zfssa/hol9715/datafiles export: /zfssa/hol9715/fra mount: /zfssa/hol9715/fra export: /zfssa/hol9715/logs mount: /zfssa/hol9715/logs Direct NFS, also known as dnfs, is the preferred method for database communication with the Oracle ZFS Storage Appliance. This feature optimizes I/O traffic by replacing the kernel NFS with an NFS client that is tailored specifically for Oracle software. It is only available in Oracle Database 11g and 12c. 10 HOL DEPLOYING ORACLE DATABASE 12C WITH THE ORACLE ZFS STORAGE APPLIANCE

14 Create an Oracle 12c Database Use DBCA to Create a Database DBCA, the Database Configuration Assistant, is a tool to create, configure, or destroy an Oracle database. It will be utilized in this lab in order to automate a database install. Contents of the DBCA Configuration File To simply the creation of the database with DBCA, a configuration file has already been pre-generated for this lab. This is an XML file that aligns the NFS shares and settings already configured with the ZFS storage appliance. $ cd /home/oow/oracle $ cat setup/hol9715.dbc <?xml version = '1.0'?> <DatabaseTemplate name="hol9715" description=" " version=" "> <CommonAttributes> <option name="oms" value="true"/> <option name="jserver" value="true"/> <option name="spatial" value="true"/> <option name="imedia" value="true"/> <option name="xdb_protocols" value="true"> <tablespace id="sysaux"/> </option> <option name="oracle_text" value="true"> <tablespace id="sysaux"/> </option> <option name="sample_schema" value="false"/> <option name="cwmlite" value="true"> <tablespace id="sysaux"/> </option> <option name="apex" value="true"/> <option name="dv" value="true"/> </CommonAttributes> <Variables/> <CustomScripts Execute="false"/> <InitParamAttributes> <InitParams> <initparam name="db_name" value=""/> <initparam name="dispatchers" value="(protocol=tcp) (SERVICE={SID}XDB)"/> <initparam name="audit_file_dest" value="{oracle_base}/admin/{db_unique_name}/adump"/> <initparam name="compatible" value=" "/> <initparam name="remote_login_passwordfile" value="exclusive"/> <initparam name="processes" value="300"/> <initparam name="undo_tablespace" value="undotbs1"/> <initparam name="control_files" value="("/zfssa/hol9715/logs/{db_unique_name}/control01.ctl", "/zfssa/hol9715/fra/{db_unique_name}/control02.ctl")"/> <initparam name="diagnostic_dest" value="{oracle_base}"/> <initparam name="db_recovery_file_dest" value="/zfssa/hol9715/fra"/> <initparam name="audit_trail" value="db"/> <initparam name="memory_target" value="250" unit="mb"/> <initparam name="db_block_size" value="8" unit="kb"/> <initparam name="open_cursors" value="300"/> <initparam name="db_recovery_file_dest_size" value="" unit="mb"/> </InitParams> <MiscParams> <databasetype>multipurpose</databasetype> <maxuserconn>20</maxuserconn> <percentagememtosga>40</percentagememtosga> <customsga>false</customsga> 12 HOL DEPLOYING ORACLE DATABASE 12C WITH THE ORACLE ZFS STORAGE APPLIANCE

17 Monitor Progress and Performance Using ZFS Storage Analytics Analytics is an advanced facility that you can use to graph a variety of statistics in real-time and record this data for later viewing. It has been designed for both long term monitoring and short term analysis. When needed, it makes use of DTrace to dynamically create custom statistics, which allows different layers of the operating system stack to be analyzed in detail. Navigate to the Analytics section While the database is installing, click on the Analytics tab on the right side of the upper taskbar. Add a Statistic On the left side of the browser, click on the + icon next to Add statistic to bring up the statistic menu. The most relevant statistics for database performance analysis can be found in the NFSv4 category. 15 HOL DEPLOYING ORACLE DATABASE 12C WITH THE ORACLE ZFS STORAGE APPLIANCE

18 Analytics has been designed around an effective performance analysis technique called drill-down analysis. This involves checking high level statistics first, and to focus on finer details based on findings so far. This allows you to quickly narrow the focus to the most likely areas. 16 HOL DEPLOYING ORACLE DATABASE 12C WITH THE ORACLE ZFS STORAGE APPLIANCE
